Python_服务器与多客户端通信、UDP协议、pycharm打印带颜色输出、时间同步的机制

1、服务器与多客户端通信

 import socket
 # 创建tcp socket的套接字
 sk = socket.socket()
 # bind
 sk.bind(('127.0.0.1',8080))
 # 监听
 sk.listen(5)
 # 等待连接
 while 1:
     conn, addr = sk.accept()
     while 1:
         msg_s = input('>>>')
         conn.send(msg_s.encode('utf-8'))
         if msg_s == 'q':
             break
         msg_r = conn.recv(1024).decode('utf-8')
         if msg_r == 'q':
             break
         print(msg_r)
     conn.close()

 sk.close()

TCP_服务器端

 import socket

 sk = socket.socket()

 sk.connect(('127.0.0.1',8080))

 while 1:
     msg_r = sk.recv(1024).decode('utf-8')
     if msg_r == 'q':
         break
     print(msg_r)
     msg_s = input('>>>')
     sk.send(msg_s.encode('utf-8'))
     if msg_s == 'q':
         break

 sk.close()

TCP_客户端
